Description

Self-bearing type steel bar truss floor support plate supporting construction
Technical field
The present invention relates to xoncrete structure architecture construction field, more particularly to a kind of support of self-bearing type steel bar truss floor support plate Structure.
Background technology
Steel bar truss floor support plate is belonging to without the one kind for supporting die mould to combine floor support plate;Steel bar girder is in backstage processing space Patterning process, site operation needs first contour plate to be fixed on girder steel using peg, then places steel bar girder and carry out colligation, tests Receive after-pouring concrete.Such as A of Chinese patent literature CN 103352563 discloses a kind of board-like bar frame combination die of self-supporting Plate, including the board-like bar frame unit of self-supporting, it includes multiple rows of longitudinal reinforcement truss, and the single longitudinal reinforcement truss is by winding up Muscle, two lower edge muscle and it is arranged on the ripple muscle composition winded up between muscle and the lower edge muscle;Multiple rows of cross direction profiles steel Muscle, the single transversely distributed steelbar is fixed with the longitudinal reinforcement truss;Detachable template, positioned at the board-like reinforcing bar of the self-supporting The bottom of unit truss is simultaneously fixedly connected with the board-like bar frame unit of the self-supporting.
Need to add temporary support in span centre in large-span steel-reinforced truss floor support plate floor slab construction, temporary support is by steel Pipe, jackscrew, lumps of wood composition, prop up and peak at floor support plate bottom, and floor support plate is not in compared with large deflection during ensureing to pour.But due to The galvanized steel plain sheet of the directly contact lumps of wood and the space of steel bar girder matcoveredn thickness, galvanized steel plain sheet deforms in support top position when pouring The negative amount of deflection of generation is put, the protective layer thickness of reinforcing bar and the outward appearance of concrete is affected.As shown in Figure 1, 2, large-span steel-reinforced truss building The general support top scheme of board is that steel bar truss floor support plate includes wind up reinforcing bar 101, lower edge reinforcing bar 102, web member reinforcing bar 103, plating Zinc steel plate 100 and fastener 200, fastener 200 is arranged on web member reinforcing bar 103 and galvanized steel plain sheet 100 for clasping the web member Reinforcing bar 103 and galvanized steel plain sheet 100, due to fastener 200 it is downwardly projecting in the lower surface of the galvanized steel plain sheet 100, therefore can only be by Support component 1 is arranged between two row's fasteners 200 to be located, herein the reinforcing bar 101 that winds up of in the vertical direction correspondence steel bar girder, on String reinforcing bar 101 is not contacted with galvanized steel plain sheet 100 and has very big space, and when floorslab concrete is poured, steel plate can be produced at support top The cover to reinforcement that negative amount of deflection deformation is finally filled into herein is thinning, and floor can also produce obvious open defect.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome defect of the prior art, will not so as to provide one kind Deform galvanized steel plain sheet, both ensure that floor presentation quality in turn ensure that the self-bearing type reinforcing bar purlin of the thickness of protection tier of filling Frame floor support plate supporting construction.
To achieve these goals, a kind of self-bearing type steel bar truss floor support plate supporting construction of the invention, including reinforcing bar purlin Frame floor support plate and the support component below the steel bar truss floor support plate;The steel bar truss floor support plate includes the steel that winds up Muscle, lower edge reinforcing bar, web member reinforcing bar, galvanized steel plain sheet and fastener, the galvanized steel plain sheet is located at the lower section of the lower edge reinforcing bar and leads to Cross fastener to fix with the web member reinforcing bar;The support component withstands the galvanized steel plain sheet, and the support component is supported in The underface of a part in the web member reinforcing bar and some contact points of the galvanized steel plain sheet, the position is the galvanized steel The supporting part of plate lower surface;The fastener is arranged in the web member reinforcing bar and some contact points of the galvanized steel plain sheet and removes position The position of other contact points of contact point directly over the supporting part.
The support component includes the elongated lumps of wood and withstands the steel pipe of the lumps of wood.
Jackscrew is additionally provided between the steel pipe and the lumps of wood.
The contact site is linear areas always, and arranges with the lower edge parallel reinforced steel bar.
The span of the steel bar truss floor support plate is L, as 3.3≤L < 6.6m, in span centre one support component is arranged.
The span of the steel bar truss floor support plate is L, as 6.6≤L < 9.9m, in span centre twice support component is arranged.
The contact site is linear regions always, and arranges into angle with the lower edge reinforcing bar.
The angle is 90 °.
Using above-mentioned technical proposal, the self-bearing type steel bar truss floor support plate supporting construction of the present invention, compared with prior art, The thickness of protection tier filled can effectively be ensured, the deformation of zinc-plated steel form is effectively reduced, be conducive to later stage steel form Recycling;The flatness of concrete floor, presentation quality have great lifting.
